A coal pile temperature measurement and cooling grouting device and system

Abstract

The invention discloses a temperature measurement and cooling grouting device for coal piles, which comprises an outer-layer rounded truncated body, an inner-layer rounded truncated truncated body and a self-moving heat pipe. The top of the rounded truncated truncated body is an open structure, the bottom of the rounded truncated truncated body is provided with an outer truncated truncated body bottom plate, the top of the inner-layer truncated truncated truncated body is provided with an inner-layer truncated truncated body top plate, and the bottom is provided with an inner-layer truncated truncated body bottom plate, and the lower end of the self-moving heat pipe passes through the inner layer The top plate of the round table extends into the middle and lower part of the inner round table; the outer side walls of the outer round table are provided with fins, a plurality of thermocouples are installed on the fins, and a plurality of outer round round tables are opened on the outer round table. For the slurry outlet, the inner-layer rounded table body is provided with a plurality of slurry outlet ports of the inner-layer rounded table body, and a grouting system is arranged on the inner-layer rounded table body. The invention also discloses a coal pile temperature measurement and cooling grouting system. The invention can monitor the temperature of the coal pile in real time, can cool the coal pile through the self-transfer heat pipe, can accurately cool the coal pile through grouting, and has a good cooling effect.

Description

technical field [0001] The invention belongs to the technical field of preventing spontaneous combustion of coal piles, and in particular relates to a coal pile temperature measuring and cooling grouting device and system. Background technique [0002] my country is rich in coal resources, and there is a great demand for coal in coal mines, large chemical companies, steel plants, thermal power companies, cement plants, coking plants, metallurgical plants, etc. Spontaneous combustion of coal piles occurred, causing massive property losses. Therefore, it is necessary to monitor the temperature of the coal pile and take cooling measures when the temperature of the coal pile is too high. [0003] The phenomenon of spontaneous combustion of coal piles is due to the oxidation of coal in contact with air and the release of heat. The excessive accumulation of coal leads to the inability to dissipate the heat generated by oxidation in time, which gradually increases the temperature o...

AI Technical Summary

Problems solved by technology

Spraying the surface of the coal pile with water directly or digging trenches for irrigation will make the amount of water infiltrated into the coal pile uneven and easy to lose, and it is easy to wash away the coal or soak the wall

Due to the small amount of water entering the spontaneous combustion part under the action of heat and pressure, the fire prevention effect is not good
